This invention relates to pressing elements for pressing machines and has for its ob]ect, a particularly simple and economical construction of a pressing element or headformed for the most part of sheet metal.

. The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference 1s I '.0 had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is a plan view of a press head embodying my invention. u Figures 2 and 3 are sectlonal v ews taken respectively, on lines 2-2, 3-3, F1gure 1.

Figure 4 is a fragmentary 'side elevatlon of a pressing machine. .1

This pressing element or head for pressing machines com rises a press plate, a second plate overlying the press plate and formed of sheet metal and fixed to the press plate, a third plate overlying the second plate of sheet metal and having its margm secured to the second plate and intermediate portions offset from the second plate and together therewith forminga chamber for a fluid medium. The press plate is spaced from the second plate to form a chamber for a heating medium,as steam, the press plate is also perforated, and a valve controlled conduit connecting the chamber and the space between.

the press plate and the second plate.

1 designates the press plate which 1s usually a casting of thick unflexible sheet steel, and 2 designates the second plate of sheet metal overlying the press plate 1 and spaced therefrom, the plate 2 being secured along its margins to the plate 1 and being spaced at its margins from the plate 1 by s acing strips 3.- The plate 1 is also forme with perforations 4. throughout its extent and these perforations communicate with the space between the plates 1, 2. This space is usually filled with a heat distributing medium as metal wool 5. we

A third plate 6 is secured at its margins to the plate 2 and .has its intermediate portions offset to form a chamber for a heating 60 medium as steam. As illustrated, the plate 6 is formed with lengthwisecorrugations which terminate short of the ends of the plate. Alternate corrugations rest upon and are secured to plate 2 as by welding. The intermediate corrugations provide passageways over the top of plate 2. It will be noted inasmuch as these co tions terminate short of the ends of the plate 6 of which they are formed, the passageways formed by the intermediate corru ations open into a chamber common to all t e corrugations, thus providing for the circulation of the heating medium over a comparatively large portion of the surface of the plate 2.4

A suitable inlet 8 is provided at one end for steam and an outlet 9 at the other end; Usually, the corrugated plate 6 is overlaid with a sheet of'heat insulating material 9 and also by a sheet metal cover plate 10, the sheet ofheat insulating material 9 and the outer sheet metal cover plate 10 are secured at their margins to the margin of the plate 6.

11 is a carrier by means of which the head is secured to a yoke lever 12 of a pressing machine. This carrier is connected to the press head 1 so that the straln or weight of the head is carried by the cast plate 1. The carrier 11 is connected to the press plate 1 by studs 13 slidable through the carrier 11 and I extending through the plate 10, insulating sheet 9 plates, 6 and 2 and threading into the 'press plate 1, these studs extending through the. alternate corrugations of the plate 6' which are secured to the plate 2. Spacers or gaskets 14 are usually interposed between the plates 1 and 2.

A conduit connects the steam chamber formed by the corrugated plate .6 and the space between'the plates'l and 2. This conduit comprises twosections 15 and 16 and a valve 17 connecting the sections. The section 15 opens into the chamber between one of the corrugations of the plate 6 and the plate 2; the section 16 extends through the space between two of the corrugations and ally operated and extends through an opening 18 in the carrier 11.

' through the plate 2. The valve 17 is manu- In Figure 4, is shown one type of machine 1 in which this pressing element is used, and

althdugh the'head above described is formed of sheet metal, either the head or the buck B or-both may be formed of sheet metal. The buck B is stationary and suitably mounted on the frame F. The yoke lever 12 which carries the head is carried by the frame and actuated by any suitable mechanism carried by the frame.

The construction of the head is particular- 1y economical and owing to the space between the plates 1 and 2, the steam that is to be projected through the perforations is maintained hot enough so that it will not condense while being distributed throughout the plate 1.
